After adopting technique scheme, with traditional structure, compare, the utility model arranges the typing breach in the bending place of electrical connector, smaller being not easy of stress of the rear resilience of electrical connector bending rebounded, therefore easily typing, the high conformity of product, rate of finished products gets a promotion.
The accompanying drawing explanation
By below in conjunction with accompanying drawing, the utility model being described, above-mentioned feature of the present utility model and technological merit will become apparent and easily understand.
Fig. 1 is the explosive view of the utility model microphone device;
Fig. 2 is the perspective view of the utility model microphone device;
Fig. 3 is the perspective view of the utility model microphone device electrical connector.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to further detailed description.
As Fig. 1 to as shown in, microphone device involving vibrations system of the present utility model, magnetic circuit system, electrical connector 4, and the shell 12 of accommodating fixing above part.Wherein, vibrational system comprises vibrating diaphragm and is incorporated into the voice coil loudspeaker voice coil 22 of vibrating diaphragm near magnetic circuit system one side, vibrating diaphragm comprises the ball top 210 and the ring section 12 that is positioned at marginal position of the rigidity that is positioned at center, and ring section 12 can make vibrating diaphragm up-down vibration freely for the material of relative flexibility.Magnetic circuit system is that two magnetic route structure comprises the internal magnetic circuit that is positioned at center and the external magnetic circuit that is positioned at marginal position, internal magnetic circuit comprises interior washer 311 and internal magnet 312, external magnetic circuit comprises outer washer 321 and external magnet 322, and internal magnet 312 and external magnet 322 are combined with the basin frame 33 of magnetic conduction away from a side of vibrating diaphragm.Wherein, magnetic circuit system forms the magnetic gap accommodate voice coil loudspeaker voice coil 22, and voice coil loudspeaker voice coil 22 is connected after the signals of telecommunication forced vibration in magnetic field, further drives the generation of vibration sound of vibrating diaphragm.In addition, also comprise electrical connector 4, electrical connector 4 is electrically connected to voice coil loudspeaker voice coil 22 and external circuit, by external circuit, realizes the control to the electro-acoustic element signal.
As shown in Figures 2 and 3, electrical connector 4 is the metal clips structure, and an end of electrical connector 4 is combined with shell 12 injection mouldings, and the part of exposing shell 12 is hung on shell 12 through the bending rear overhang.Electrical connector 4 comprises deformations 41, the kink 43 engaged with shell 12, and the connecting portion 42 that connects deformations 41 and kink 43.Wherein, deformations 41 is provided with the terminal with shell 12 free combinations away from the end of kink 43, and the end away from vibrating diaphragm one side of deformations 41 directly contact the realization electrical connection with the pad of external circuit.Kink 43 is provided with the first typing breach 431 that material forms, the first typing breach 431 can be arranged at the one or both sides of electrical connector 4, the both sides that the present embodiment the first typing breach 431 is arranged at electrical connector 4 are symmetrically arranged structure, the present embodiment the first typing breach 431 is arcuate structure, but is not limited to this structure.
This structure that is provided with the first typing breach 431 of material formation on the kink 43 of metal elastic sheet electrical connector 4, the kink 43 of electrical connector 4 bendings goes to expect that the width of rear formation is less, thereby after electrical connector 4 bendings, smaller being not easy of stress of resilience rebounded, therefore easily typing, the high conformity of product, rate of finished products gets a promotion.
